Description

[Detailed Description of the Invention] (Industrial Application Field) This invention provides decorative tiles on a reinforced concrete plate containing inorganic mis such as alkali-resistant glass fiber and carbon fiber (hereinafter referred to as GRC and CRC, respectively). This invention relates to improvements in decorative tile boards, particularly to decorative tile boards made of foamed concrete boards that are lightweight and prevent the board from warping.

(Prior art) Conventionally, decorative boards with decorative tiles have been made of reinforced concrete boards mixed with inorganic fibers such as GRC and CRC, which are thin but strong and do not chip or crack. There was something that was used.

(Problem to be solved by the invention) However, in the case of fiber-filled reinforced concrete plates, the fibers mixed into the concrete due to the vibration seal added to narrow down the concrete during the forming of the plate will cause the fibers to flow downward at both ends within the concrete. When the tiles are formed in a hanging state with the fiber direction aligned, and the non-decorative side of the tile is buried in one side of the concrete plate, the thick part between the tiles and the thin part of the tile buried part are There was a problem that the concrete plates would warp because they were placed alternately.

In addition, in order to efficiently draw out the tensile force of the mixed fibers, residual air is forcibly removed by applying vibration or squeezing during molding, and the mixing water is squeezed as much as possible during molding, so the density tends to increase. As a result, even though it was thinner, the weight was not much lighter, and furthermore, because it was thin and had a high compositional density, the sound transmission rate was high and the soundproofing effect was low.

Furthermore, since the total volume of internal remaining voids is similarly small, no insulation effect can be expected and separate insulation construction is required.

Furthermore, in this type of fiber-reinforced concrete plate, since the mixed rain is tightly contained within the concrete structure, it provides a place for water drainage by the typical capillary phenomenon, and rainwater is removed from the edges of the concrete plate. There were problems such as moisture seeping into the board and causing stains on the board surface.

(Means for Solving the Problems) The present invention has been proposed to solve the above problems, and includes a plate-shaped decorative tile 2 on one side with its non-decorative side 2a inside the board 1. In the decorative tile board that is embedded in the tile board, the board l is made of alkali-resistant glass fiber.

It is a foamed concrete board reinforced with inorganic A183 such as carbon fiber, and all or part of the foamed form of the board 1 is discontinuous to prevent the board 1 from warping and to improve sound insulation properties. It was designed to increase the

(Example) A typical example of the present invention will be described below with reference to the drawings.

1 is a board, 2 is a plate-shaped decorative tile, and board l
Decorative tiles 2.2... are integrally embedded with their non-decorative side 2a buried in one side of the board 1, and the board 1 is made of foamed concrete 4.1 The foamed concrete 4 is made of inorganic fibers 3.
The fiber Jii3 is easily blended with cement, has high durability, and has high tensile strength. Typical examples are alkali-resistant glass fiber,
Carbon fiber, Kepler fiber, asbestos, and other ceramic fibers are used, and ideally they are evenly mixed in the form of short fibers.

The cement used is selected appropriately depending on the purpose. Basically, the sand and cement slurry mixed with mixing water and the fibers 3 are blown out from nozzles on different sides, and poured into the mold so that they are evenly mixed with each other. In this state, a foaming agent mixed in the slurry brings closed cell-like air bubbles 5 to the poured concrete, thereby forming a board l made of foamed concrete 4 reinforced with fibers 3 and in which the air bubbles 5 are discontinuous with each other. It is something that will be done.

In addition, it is not the molding method mentioned above, but fiber #I3.

Another method is to knead sand and cement in a dry state, add a foaming agent and water to the mixture, and then pour the mixture into a mold.

Furthermore, there is also a method of foaming and curing after extrusion using an extrusion device.

Further, FIG. 2 shows an embodiment in which omniar reinforcing bars 6 made of wavy bent reinforcing bars are arranged inside the board 1 to further increase the strength of the board 1 and prevent the occurrence of bending or cracking. It is.

(Effect) In the decorative tile board formed by the above method, the board l in which the decorative tiles are embedded has fibers 3 intertwined vertically and horizontally within the foamed concrete 4 constituting the board l, and the structure between the fibers 3 is Since the air bubbles 5 press the slurry against the fibers 3, the fibers 1 always exist within the solidified flesh of the dense slurry, and are not left in the air bubbles 4a, and the fleshy portion is made of alkaline glass fiber, carbon fiber, etc. Since the concrete plate is reinforced with inorganic fibers and all or part of the foamed form is discontinuous, there is no risk of the fibers 3 slipping out from the solidified fleshy part of the concrete. It is tightly fixed by the coagulated fleshy part, so that the board 1 does not warp or the like. This also means that despite having the bubbles 5, the bending strength as a fiber reinforced plate is not impaired in any way.

Furthermore, due to the presence of the air bubbles 5, the water that infiltrates the m-fibers 3 by capillary action is dissolved in the air bubbles 5, which means that the water wetting phenomenon occurs only in areas relatively close to the surface. There are advantages in producing C.

Furthermore, since the bubbles 5 are in a closed cell type, the inherent vibration of the sound transmitted through the solidified flesh of the concrete plate is blocked within the bubbles 5, or is repeatedly reflected and absorbed, and is rapidly attenuated. This means that effective sound insulation is possible.

Furthermore, since the cells 5 are in a closed cell form, the concrete plate itself has high heat retention, and there is no convection of the retained hot air, making it possible to provide effective heat insulation.

Furthermore, since the bubbles 5 are structurally closed cell type,
The solidified fleshy part constituting the outer shell of the bubble 5 has a honeycomb-like structure, and these honeycomb-like structures are further connected by m-fibers 3, so that even though it is a foam structure, it can be compressed. It is characterized by particularly good strength and bending strength.

Furthermore, by arranging omnia reinforcing bars within the board as in the embodiment shown in FIG. 2, a decorative tile board with even higher bending strength and tensile strength can be obtained.
